An agreement for the marriage you actually have
Prenups are signed by couples guessing at a future. Postnups are signed by couples who know their marriage: the business that took off, the inheritance that arrived, the rough year they got through. That knowledge is exactly why Singapore’s courts take a well-made postnup seriously.
I’m Wahab. I run A.W. Law LLC in Chinatown, and the couples who sit across my desk for postnups are rarely in crisis. They’re reorganising: a parent’s gift to protect, a company to insulate, a reconciliation to put on firmer ground.
The first 10 minutes are free, and nothing commits you.
What a postnuptial agreement in Singapore actually is
A postnup is a written agreement between spouses, made after the wedding, recording how assets and financial responsibilities are held and how they’d be divided if the marriage ended. The legal frame is the Women’s Charter: in a divorce, section 112 gives the Family Justice Courts the final say over dividing matrimonial assets, and directs the court to weigh any agreement the spouses made.
So the honest position is this: a postnup is a valid contract, and in a divorce it’s a weighty factor rather than an automatic rulebook. The Court of Appeal held in TQ v TR [2009] SGCA 6 that postnuptial agreements may attract more weight than prenups, precisely because both spouses sign knowing the marriage rather than guessing at it. Later decisions have confirmed that an agreement made freely, with independent advice and full disclosure, can carry significant weight, and one made in contemplation of an actual divorce carries more still.
What determines the weight, in practice:
- Free agreement. No pressure, no ultimatum, no signing the night before a flight.
- Full disclosure. Each spouse knew what the other owned. Hidden assets sink postnups.
- Independent advice. Each spouse had their own lawyer look at it.
- Basic fairness. An agreement leaving one spouse with nothing invites the court to discount it.
- What happened after. An agreement both spouses followed for years reads very differently from one signed and ignored.
One firm boundary: the children. Custody, care and control, access, and child maintenance are always the court’s decision on the child’s welfare. A postnup can record intentions about the children; it cannot bind them. Our child custody page explains how those decisions are actually made.
When a postnup is the right tool
The situations that bring couples to this document:
- An inheritance or family gift. Parents passing assets down often want them kept out of any future division. A postnup, sometimes paired with a will, records that intent while everyone is on good terms.
- A business. A founder spouse wants the company insulated from matrimonial risk; the other spouse wants the home and provision secured in exchange. That trade is the classic postnup.
- After a rough patch. Couples who’ve reconciled sometimes want the financial terms of the fresh start written down. Courts understand these agreements well.
- Updating a prenup. Circumstances outgrow the original document. See our prenuptial agreements page for how the two relate.
And the boundary case: if you’re not reorganising the marriage but ending or pausing it, the right document is a deed of separation, which is built for couples separating. At the Discovery Session, telling me which of these is really happening takes one sentence, and it changes everything about the drafting.
What to expect, honestly
How long it takes.
Where both spouses broadly agree, expect 3 to 6 weeks from first meeting to signatures: disclosure schedules, a draft, each side’s advice, one or two rounds of comments. Negotiated agreements take longer.
How much it costs.
A postnup with terms broadly agreed runs S$2,000 to S$4,000 at A.W. Law. Business valuations, overseas assets, or hard negotiation push it higher. Each spouse should also budget for their own independent advice; it’s the cheapest weight-adding step there is. Fees in writing before any paid work. The 10-min Postnup Discovery Session is free.
What’s the hard part.
Raising it. Asking your spouse to sign a postnup can sound like planning for failure, and most of the awkwardness in these matters is the first conversation, not the drafting. The framing that’s true and that works: this document protects both of you from a fight neither of you wants, and it’s signed while you still like each other. The second hard part is disclosure; incomplete disclosure isn’t a shortcut, it’s a self-destruct clause.
How we handle postnups at A.W. Law
- Drafted by someone who litigates divorces. I’ve argued about these agreements at the Family Justice Courts, so I draft against the arguments I know get made.
- Plain English clauses. Both spouses should understand every line without a translator, legal or otherwise.
- Disclosure done properly. We build the schedules that make the agreement durable.
- Independent advice arranged. We act for one spouse and help the other find their own lawyer, because that separation is what protects the document.
- WhatsApp until 10pm on weekdays.
We’re at 133 New Bridge Road, #20-03 Chinatown Point. Two minutes’ walk from Chinatown MRT, Exit E.
