What is a Postnuptial Agreement?
It is used by spouses, partners and families who want the terms recorded before work starts or money changes hands, rather than reconstructed from memory afterwards. Putting it in writing is what turns an understanding into something either side can rely on.
13 details are captured across 5 areas: parties and contact details, scope and deliverables, payment and financial terms, dates, timing and duration, and legal protections and risk. Together they fix what each party owes the party transferring, measured in asset addresseds rather than in adjectives.
The recurring failure in this kind of arrangement is an agreement signed without independent advice on both sides. Private agreements between people who trust each other are the ones least likely to be written down and most likely to end a relationship when they go wrong. The written record is the point.

What matters most in a postnuptial agreement
Timing affects validity
An agreement signed shortly before a wedding may be attacked as made under pressure. Sign well in advance.
Courts retain oversight over children
Arrangements for children are always subject to the court's assessment of their best interests, whatever the parents agree.
Independent legal advice is close to essential
Prenuptial and separation agreements are routinely challenged. Independent advice for each party is one of the strongest factors supporting enforceability.
When you need a postnuptial agreement
- When the financial arrangement needs defining: Write down what is included and what is not. A specific description is what turns an extra request into a chargeable variation rather than an argument.
- When either side may need an exit: Agree how the arrangement ends while both parties are still on good terms. Exit clauses negotiated during a dispute rarely favour anyone.
- When more than one person is involved: Where several people share the obligation, the postnuptial agreement should say whether they are liable together, separately, or both. That single word decides who can be pursued for the whole amount.
- When money changes hands: Record what the party transferring owes, when each asset addressed falls due, and what follows a late payment. These are the clauses relied on most often and left vague most often.
- When risk needs allocating: Decide who carries which risk and who insures it before an incident rather than after one. Afterwards, both readings of the silence are self-serving.
- Before each party starts: Put the postnuptial agreement in place before anyone relies on it. An agreement signed after work has begun is far harder to enforce on the terms you actually intended.
What to include in a postnuptial agreement
This generator collects 13 details. Here is what each group covers and why it matters when the document is relied on.
Parties and contact details
Everything else in the document hangs off these names: each party carries the obligations, the party transferring carries the payment, and both need identifying precisely enough to be found later.
- Spouse One Name
- The first spouse's full legal name as it appears on the marriage record.
- Spouse One Address
- The first spouse's current address for notices.
- Spouse Two Name
- The second spouse's full legal name.
- Spouse Two Address
- The second spouse's current address for notices.
Scope and deliverables
This is the section that decides arguments. Describe the financial arrangement in asset addresseds and against the full financial disclosure exchanged beforehand, so that whether it has been delivered is a question of fact rather than opinion.
- Purpose of Agreement
- Why the parties are entering into the agreement. This helps a court interpret ambiguous clauses in line with the parties' actual intent.
- Responsibilities
- What each party must do, provide or approve, allocated by name so no obligation is left unowned.
Payment and financial terms
Payment terms are relied on more often than any other clause and left vague more often than any other clause. State the amount, the trigger, the deadline and what follows a late payment.
- Amount or Property
- A precise description of the money or property being transferred, with quantities and identifying details.
- Payment Terms
- The invoicing cycle, payment window, accepted methods and consequences of non-payment.
Dates, timing and duration
These dates decide when obligations start, when they end, and when someone is in breach. The effective date in particular should have a date and a test attached to it.
- Effective Date
- The date the agreement takes effect. This can differ from the signature date, and it is the date obligations start running from.
- Schedule
- The agreed timetable of dates, sessions or milestones.
- Notice Period
- How much warning a party must give before ending the agreement, and how notice must be delivered to count.
Legal protections and risk
Decide who carries which risk and who insures it before an incident, not after. Afterwards, both readings of the silence are self-serving.
- Default Terms
- What counts as a default, any cure period, and the remedies available to the non-defaulting party.
- Governing State
- The state whose law governs the agreement. Choose a state connected to the parties or the work, as a wholly unconnected choice may not be respected.
Completing this postnuptial agreement
Keeping the version straight
Date the document and mark superseded drafts clearly. Two unlabelled versions in circulation is a surprisingly common cause of genuine, honest disagreement.
Making the counts checkable
Where the price depends on asset addresseds, keep a contemporaneous record as they are delivered. A count reconstructed at invoice time invites a challenge that a running record would have prevented.
Reading it as the other side would
Before signing, read the postnuptial agreement from the counterparty's position and look for anything you would exploit. If you find something, so will they.
Defining the effective date
Say what has to be true for the effective date to have happened and who confirms it. An undefined completion test is the reason obligations sit open long after the work is finished.
Signing and keeping it
Every party named should sign and date, and each should keep their own copy. Electronic signatures are valid for the great majority of agreements — retain the audit trail showing who signed and when.
Common mistakes to avoid
- Overlooking third-party consents. Where a landlord, lender, insurer or regulator has to agree, get that consent before the effective date rather than assuming it will follow.
- Leaving out the governing law. Where each party and the party transferring are in different places, naming the law and the forum in advance avoids a preliminary fight about where the dispute is even heard.
- Verbal instructions on top of a written contract. Once instructions start being given by phone or in passing, the written agreement stops describing the arrangement. Confirm changes in writing the same day.
- Relying on the relationship. Private arrangements are agreed between people who trust each other and enforced between people who no longer do. Write it down while everyone is still friendly.
- No mechanism for changes. Things change after signature. A short variation clause — changes in writing, signed by both, priced before they start — costs nothing to include and settles the argument before it begins.
How to use this postnuptial agreement generator
- Fill in the form. Work down the 13 fields in order. The ones describing the financial arrangement carry the most weight, so give them more than a few words — everything else in the document refers back to them. Nothing is sent to a server — the document is assembled in your browser.
- Read the preview. Check the preview against the full financial disclosure exchanged beforehand. Where the two disagree, the document is the version that will be relied on, so fix it here.
- Download and sign. Export as PDF to sign, or as Word to keep working on it. Store the signed version somewhere both each party and the party transferring can find it, along with the full financial disclosure exchanged beforehand.
Postnuptial Agreement — frequently asked questions
Are prenuptial agreements enforceable?
Generally yes, but they are scrutinised more closely than ordinary contracts and the requirements vary by state. Courts typically look for full financial disclosure by both parties, independent legal advice, no pressure or last-minute signing, and terms that are not grossly unfair. Because a defective agreement may be disregarded exactly when it is needed, this is one document where using a template without a lawyer is a false economy.
What is the most important thing to get right in a postnuptial agreement?
The description of the financial arrangement. Almost every later clause — price, timing, whether the effective date has been reached — refers back to it, so an imprecise description there weakens the whole document. State it in asset addresseds and attach the full financial disclosure exchanged beforehand rather than relying on a general description both sides read differently.
What records should I keep alongside the postnuptial agreement?
The full financial disclosure exchanged beforehand, the signed document itself, and a contemporaneous note of anything agreed afterwards. Most disputes turn on what was agreed at the time, and the party who can produce a dated record is the party who wins that argument.
Which state's law should govern this postnuptial agreement?
Choose a state with a genuine connection to the parties or the subject matter — where a party is based, or where the work or property is located. A choice with no connection at all may not be respected, and for property or employment the local state's rules will often apply regardless of what the contract says.
How is notice properly given under this agreement?
Follow the notice clause exactly: use the stated method, send it to the address named in the agreement, and keep proof of delivery. Notice given informally — a text message, or an email to the wrong person — is frequently challenged, and a defective notice can leave the agreement running on.
What interest rate can I legally charge?
State usury laws set the ceiling, and it varies widely. Some states also treat loans differently depending on whether the lender lends regularly. Check your state's limit before setting a rate, since exceeding it can cost you the interest and occasionally more.
Does this document need to be notarised?
For most private agreements, no — signatures from both parties are enough. Notarisation is worth it for larger sums, anything secured against property, or where you anticipate the document being challenged, because it makes the signature very difficult to deny.
Is my information stored anywhere?
No. Everything you type is processed in your browser and the document is assembled on your own device. Nothing is transmitted to a server, saved to an account or shared, which is why closing the tab clears your entries.
