A well-written post-nuptial agreement can help spouses manage the financial aspects of their marriage and carries significant weight in court. IRB Law’s family lawyers can assist in drafting tailored post-nuptial agreements that serve your best interests, protect your legal rights, and are recognised by the courts in Singapore.

What Is a Post-Nuptial Agreement

In Singapore, a post-nuptial agreement is a written legal contract between spouses that regulates what happens during marriage, in case the spouses decide to divorce or separate, or if one of them passes away. Unlike a pre-nuptial agreement, a post-nuptial agreement is concluded after the spouses become officially married.

The spouses can enter into a post-nuptial agreement at any time during their marriage. The Singaporean courts recognise post-nuptial agreements as valid contracts if their terms meet the contract law requirements and do not conflict with the Women’s Charter and public policy.

Why Couples Consider Post-Nuptial Agreements in Singapore

When married spouses enter into post-nuptial agreements, most often they have certain circumstances or issues arising out of the marriage which they want to regulate. Among others, such aspects may include:

Financial Arrangements During Marriage

One of the reasons to enter into a post-nuptial agreement includes regulating financial obligations during marriage, for example, paying bills and expenses, or regulating debts.

Asset Ownership Rights

In case one of the spouses has significant family wealth or expects an inheritance, the spouses may want to clarify legal issues related to possession and control over such assets in the post-nuptial agreement.

Division of Assets in Divorce

When spouses contemplate a potential or pending divorce, by signing a post-nuptial agreement, they can agree between themselves on the division of assets according to their personal preferences. By having a post-nuptial agreement in place, the divorcing spouses can further avoid potential disputes and speed up the divorce process.

Maintenance Payments

Similarly, the spouses can agree among themselves on the form and amount of spousal maintenance and financial support that one of them will receive from the other in the event of divorce or separation.

Enforceability of Post-Nuptial Agreements in Singapore Courts

The Women’s Charter provides that the courts should consider the arrangements made between the spouses in post-nuptial agreements regarding division and ownership of matrimonial assets. Also, in most cases, the courts give more weight to post-nuptial agreements compared to pre-nuptial contracts.

At the same time, post-nuptial agreements are not automatically enforceable since they must meet all legal requirements for contracts in Singapore. The court has the discretion to disregard any clauses of the postnuptial agreement which are unjust, unfair, unreasonable, or contradict Singaporean law.

I would like to sincerely thank Mr. Mohamed Baiross and his law firm. At a time when we were feeling extremely helpless and urgently needed assistance, he was willing to step in and offer help, even during the weekend. His entire team was also incredibly cooperative and supportive throughout the process, making everything much smoother and reassuring. This clearly shows that his firm is not just about business, but is genuinely committed to helping people in need. It gave us comfort and hope at a very critical moment, and we are truly grateful for their sincerity, dedication, and teamwork. Thanks you🙏🏻

I would like to express my heartfelt gratitude to Mr Baiross, Mr Basheer and Team IRB who handled my case with a positive outcome that was beyond my expectations. Mr Baiross and Mr Basheer provided me with detailed sound legal analysis, offered the available options, recommended the actions I needed to take to strengthen my case and strategized the approach taken. They were always patient in explaining the legal jargons to me so that I can make informed decisions. IRB's charges were also highly competitive and they often graciously go the extra mile. IRB indeed lives up to be a Singapore's Best Law Firm, and I highly recommend them to anyone in need of legal advice.

We hired IRB to draft an agreement and handle a commercial dispute. IRB proved to be efficient, fast and responsive, including replies over the weekend and public holidays. Comparatively, our legal opponent's lawyers were slow and often cut off work at 5 pm, despite the fact that the settlement negotiation proposed by their client had a short deadline - they also claimed to be Straits Times Singapore's Best Law Firms. We had used other lawyers and notaries in the past, including hiring a well-advertised law firm to handle a fraud case, but it turned out to be disappointing because they gave poor advice and were expensive. Overall, IRB proved to be outstanding in giving speedy, concise advice and was cost-effective. Thanking Baiross, Crystal and team!

Our company recently had the pleasure of working with Mr Baiross, Ms Crystal, Mr Quek and Mr Desmond from IRB for our civil case, and we cannot recommend IRB team highly enough. From the moment we walked into their office, we felt welcomed and understood. The team took the time to listen to our concerns and explain the legal process in a way that was easy to comprehend. Their expertise in civil law is evident; IRB guided us through every step with professionalism and care. IRB team was always quick to respond to our emails and calls, making us feel like a priority throughout the entire process. Their attention to detail is remarkable, and we appreciated how they prepared for each meeting with comprehensive notes and strategies. One of the aspects we were most impressed with was their negotiation skills. They were able to secure a favorable settlement that exceeded our expectations. It was clear that they had our best interests at heart, which made a stressful situation much more manageable. The fees were transparent, and there were no hidden costs, which we greatly appreciated. IRB provided a clear breakdown of their charges from the outset, and we felt that their rates were reasonable for the level of service provided. Overall, we are extremely satisfied with the outcome of our case and grateful to have had Mr. Baiross by our side. If you're looking for a knowledgeable, compassionate, and dedicated team of lawyers, look no further than IRB Law.

Expressing my sincerest gratitude for the excellent legal support and professionalism provided by Sharifah Nabilah throughout our case. Nabilah joined our team later but at a crucial point. She was so committed to our case and got herself up to speed in no time. I enjoyed having her on my team and working with her, making my entire case ordeal that much more bearable. Her legal arguments and writing are cogent - she is definitely born to be a lawyer, as I always tell her. Such a blessing to have met her and to have had her fight our case for us. Also a special mention to Mr Baiross, without whom none of this would be possible. He is such a compassionate lawyer, and always reminded us that all of this is a test from God, and to be patient. It kept us grounded and gave us strength to go through this ordeal. Well, thanks to the awesome team at IRB, we won our case and got a rather favourable outcome. Very thankful and would recommend to anyone in need of expert legal counsel.

General Questions

Frequently Asked Questions

What are the benefits of having a post-nuptial agreement?
When the spouses enter into a post-nuptial agreement to regulate what happens in their marriage or in case they divorce, they can bring more clarity into the relationship and financial situation. By having a post-nuptial agreement, the spouses can determine their rights related to family wealth, inheritance, or division of assets during divorce.
Do I need a post-nuptial agreement?
There is no legal requirement for spouses to have a pre-nuptial or post-nuptial agreement. Also, the Women’s Charter and civil law in Singapore provide a clear legal framework regulating the division of assets during divorce, spousal maintenance and other matters related to marriage, divorce, or separation.

At the same time, if you want to have a tailored plan as to possession and ownership of family wealth or the distribution of assets during your marriage or in case of divorce, you can regulate these and other financial matters with your spouse in a post-nuptial agreement.

Are post-nuptial agreements valid?
The Women’s Charter requires the Court to give consideration to post-nuptial agreements regarding division and ownership of family assets. At the same time, the court can disregard pre-nuptial or post-nuptial agreements that do not meet the requirements for valid contracts in Singapore or that contradict the law. For this reason, it’s always recommended to involve experienced family lawyers to ensure a valid and enforceable post-nuptial agreement in Singapore.
Can a post-nuptial agreement regulate the custody of children?
In deciding the matter of child custody, the Women’s Charter requires the courts to give paramount consideration to the welfare of the child. Accordingly, a post-nuptial agreement regulating child custody can only be valid if the spouses can clearly demonstrate that it pursues the best interests of their child.
Do we both need a lawyer for a post-nuptial agreement in Singapore?
There is no legal requirement that each of the spouses should be represented by their own lawyer when signing a post-nuptial agreement.

Meanwhile, it is always recommended to have independent legal advice for each spouse. Additionally, it’s good practice to have a written clause acknowledging that each spouse has received independent legal advice and fully understands the implications of the agreement to avoid a possibility of the agreement being invalid.
