Logically, the first thing to do when you want to get a marriage agreement is to talk to your partner. Do they mind signing a marriage contract? Do they have any concerns about it? What exactly would they like to include in such a document, and do they accept your wishes?
Also, we would advise you to study this topic on your own (or consult a specialist) before talking to your partner. This way, you can see what people usually add to their marriage contracts and how to correctly include needed clauses in the prenup, a common practice that you may not have even thought about, such as division of property, support for marital life, and division of debts.
Be as open and honest as possible in this conversation and, possibly, show your partner a sample of such a marriage contract (you can even show them a template) so that your spouse understands what you mean and what you are talking about looks like in practice.
Then, when both you and your partner agree that you will enter into such a marriage contract, find a lawyer to help you create the document. Since this process can be stressful and complicated, consider using a pre-made template — you won’t be pressured by time and the presence of a third party when drafting a marriage agreement, and you can calmly write down all the points together in the comfort of your own home.
Be as straightforward as possible when writing down the contract terms, and don’t forget to include a provision for updating the contract if you want to change the marital agreement in the future.
Make a copy of the document for each partner, and that’s it — you have a toolkit that can protect you from many of life’s problems.
