Should You Make a Post-Nuptial Agreement in Singapore?

What is a Post-Nuptial Agreement?

A nuptial agreement is an agreement between a couple setting out what will happen if the parties separate or divorce, or if one party passes away.

If such an agreement is entered into before marriage, it is called a pre-nuptial agreement, but if it is entered into during a marriage, it is known as a post-nuptial agreement.

When can post-nuptial agreements be made?

As mentioned above, post-nuptial agreements can be made or entered into by parties after they have entered into a legally binding marriage. There is no restriction on when or at which stage of the marriage that a post-nuptial agreement may be made. The contents and objectives of the post-nuptial agreement may differ, depending at which stage of the marriage that the agreement is made. This is because there may be different concerns at play when parties decide to enter into a post-nuptial agreement.

Generally speaking, there are three main stages of a marriage that a post-nuptial agreement is entered into.

Where things are going fine and the marital relationship has not broken down yet

At this stage, a couple who decides to enter into a post-nuptial agreement tends to do so not because they anticipate or even desire the marriage to breakdown. The agreement is intended to serve the function of ‘insurance’ and provide some degree of certainty on how to deal with finances etc. should the couple divorce.

A post-nuptial agreement entered into at this stage is very similar in tone and outlook to a prenuptial agreement.

Where the marriage has already broken down and parties now wish to set out how their assets and finances are to be dealt with in the event that either party files for divorce

At this stage, the marital relationship has already broken down and the primary aim of the post-nuptial agreement is to minimise any potential fall out and reach an amicable resolution of financial matters and parenting issues for the children (if any). This also removes the element of uncertainty that would arise should parties not have a prior agreement before commencing divorce proceedings and allows both parties to plan for their separate lives and that of their children moving forward.

Where divorce proceedings have already commenced or are impending

At this stage, a postnuptial agreement serves as an amicable resolution between the parties to settle the outstanding ancillary matters. This would often include the reason for the breakdown of the marriage, parties’ agreement on how to divide the matrimonial assets, maintenance as well as custody, care and control and access for the children of the marriage.

The agreed terms which are usually reached after negotiation between parties and their lawyers or at mediation are then recorded as a binding Order of Court known as a consent order.

Difference between pre-nuptial and post-nuptial agreements

As mentioned above, the main difference between pre-nuptial and post-nuptial agreements is the point at which they are created (i.e. at which stage of the marriage).

Also, courts usually place more weight on, and thus are more likely to enforce, post-nuptial agreements as compared to pre-nuptial agreements. This is because post-nuptial agreements are presumed to reflect parties’ more recent attitudes and intentions after marriage. On the other hand, pre-nuptial agreements are generally made before parties fully understand the implications and commit to the responsibilities of marriage.

As a side note, if you have already signed a pre-nuptial agreement before getting married, you can still enter into a post-nuptial agreement after marriage, perhaps to cover issues that were not already included in the pre-nuptial agreement.

However, as mentioned above, the court may give the post-nuptial agreement more weight, if the terms of both agreements are in conflict.

Difference between post-nuptial agreements and deeds of separation

While post-nuptial agreements and deeds of separation are both entered into during a marriage, there are some key differences between the two.

For one, deeds of separation are prepared only when parties wish to separate without immediately filing for divorce, or when parties have not yet met the conditions to file for divorce. On the other hand, post-nuptial agreements can be entered into even when one’s marriage is doing well, and for other reasons that will be discussed below.

Another difference is that a deed of separation binds parties to the agreement immediately after it is created, governing the relations between the parties during the separation. On the other hand, post-nuptial agreements are not automatically binding. What this means is that the court may decide that the post-nuptial agreement is not enforceable and so, the parties’ relations do not have to be governed by it.

Notwithstanding the above, the court can choose to take nuptial agreements into account as one of the factors in determining the ancillary matters between parties.

Difference between post-nuptial agreements and wills

As stated above, a post-nuptial agreement also has a secondary function of setting out what will happen if a spouse passes on before the other. This is similar to the function of a will.

However, a will is more general than a post-nuptial agreement in the sense that post-nuptial agreements only affect the rights of the spouse, whereas the beneficiaries of a will could include persons outside of the marriage.

For example, if you wish to pass on a property to your surviving spouse only, then a post-nuptial agreement can be drafted to include such a term. However, if you wish to have the property passed on to your other family members after your demise, then a will would have to be drafted to reflect your wishes.

Are Post-Nuptial Agreements Valid in Singapore?

Yes, postnuptial agreements are valid in Singapore. However, it is important to note that such agreements are not Orders of Court and are not automatically enforceable as of right.

Postnuptial agreements must be reviewed by the courts if there is a dispute as to the terms or agreement. The enforceability of post-nuptial agreements are discussed further below.

Enforceability of Post-Nuptial Agreements

As the post-nuptial agreement is a signed agreement between the parties, it is subject to the standard rules of contract law like any other contract. This means that the post-nuptial agreement would only be valid if it meets the requirements for forming a legally valid and binding contract.

It also means that the agreement can be invalidated under the usual contractual grounds, such as if it was made under undue influence, duress, misrepresentation or mistake.

Even if the post-nuptial agreement is a legally valid contract, it is not treated as automatically binding on the parties, as mentioned above. The court can still choose not to enforce a post-nuptial agreement if it does not comply with the provisions of the Women’s Charter.


For example, a post-nuptial agreement stating that the wife cannot apply for maintenance from her husband after a divorce might not be enforceable. This is because this term of the agreement potentially goes against section 113 of the Women’s Charter, which empowers the court to order a man to provide maintenance to the wife.

The court can therefore decide to ignore that term and order the husband to pay his wife maintenance if appropriate to do so.

Division of matrimonial assets

Section 112(2)(e) of the Women’s Charter provides that when making a decision on the division of matrimonial assets, the court has to take into account (among other factors) any agreement between the parties, which includes pre-nuptial and post-nuptial agreements.

However, the court would still have to be satisfied that such a division of matrimonial assets will be “just and equitable” , before enforcing such an agreement.

Arrangements for the children

For matters involving arrangements for children after a divorce – such as child custody, care and control, and access – the court will not uphold any post-nuptial agreements that are not in the best interests of the children concerned.

For example, if in the post-nuptial agreement, a parent states that he or she will not provide the parties’ children with accommodation, clothing, food and education in the event of a divorce, the court would likely disregard such a provision.

Terms of Post-Nuptial Agreements

When drafting a post-nuptial agreement, parties are free to decide what terms to include in the agreement. However, as mentioned above, not all the terms included will be enforceable, especially if these terms go against established family laws.

A few issues that are usually discussed in post-nuptial agreements are:

  • How the couple will divide property and other assets in the event of a divorce
  • Whether maintenance has to be paid, and for how long such maintenance payments will continue
  • How the couple will divide any debts in the event of a divorce
  • Custody or care and control arrangements of children in the event of a divorce
  • How the couple’s assets will pass if either spouse dies during their marriage

Should You Write a Post-Nuptial Agreement?

It is not compulsory to have a post-nuptial agreement.

Nevertheless, entering into such an agreement should always be an informed, consensual choice by both parties. Do note that there is no one size fits all approach or a template for a ‘standard’ postnuptial agreement. A good postnuptial agreement should be comprehensive and the terms should be reasonable and accurately reflect parties’ intentions.

The table below summarises a few potential benefits and disadvantages of signing a post-nuptial agreement that you may wish to consider:

Benefits and disadvantages of writing a post-nuptial agreement

Benefits Disadvantages
Post-nuptial agreements can be used to expedite divorce proceedings and minimise the possibility of disagreement over the ancillary matters in a divorce. This is because parties would have agreed on the ancillary matters beforehand, resulting in an uncontested divorce rather than a contested divorce. Post-nuptial agreements are not automatically binding in Singapore. There is no guarantee that the court will require the parties to comply with what has been stated in the agreement.
Post-nuptial agreements can also lead to more certainty in the expectations of the parties in the event of a divorce. Parties can visualise what the outcome of the divorce proceedings is likely to be, for example, which assets they will gain after the divorce. Sometimes, broaching the idea of a post-nuptial agreement could lead to the breakdown of the marriage itself, as it may appear that the party initiating the agreement lacks trust in the other.
Post-nuptial agreements can also be useful to reflect a material change in circumstances since the parties got married (e.g. if one party obtains a large inheritance after the marriage, and wants to protect it in the event of a divorce)
Parties can use a post-nuptial agreement as a means of protecting their assets or protecting themselves from debt liability in the event of a divorce.

Can I draft a post-nuptial agreement myself? Must I hire a lawyer? 

If you and your spouse decide to go ahead with entering into a post-nuptial agreement, you can technically write the agreement by yourself.

However, because many factors can potentially cause a post-nuptial agreement to be set aside (i.e. not enforced) by the courts, it may be better to hire a family lawyer to draft the agreement to ensure that it complies with the legal requirements.

This is especially so if the terms of the agreement are complex, for example, the division of marital debts which involves the calculation of liabilities as well as present and future interest rates.

A post-nuptial agreement can be drafted by a single lawyer selected by both parties if both parties generally agree on the terms of the agreement.

However, if there may be disagreement as to the different terms to be included, each spouse should consider getting their own lawyers to advise them on their legal position on the different terms. Ultimately, there must be only one post-nuptial agreement that is signed.

Post-nuptial agreements can be a sensitive topic; you and your spouse should have a frank and candid discussion about whether entering into a post-nuptial agreement is suitable for your needs and objectives.

If you are contemplating entering into a postnuptial agreement or wondering if it is appropriate in your current situation, it is advisable to speak to a family lawyer who would be able to advise you. A lawyer would be able to advise you on what terms should be incorporated in the postnuptial agreement and whether there are any issues with the proposed settlement terms.
