To modify the marriage form to include an agreement regarding income sharing between you and your spouse, you can add a specific clause that clearly outlines the income-sharing arrangement. Here is a suggested draft for that:
"Income Sharing Agreement:
It is mutually agreed between the Wife and Husband that 30% of any income received by the Wife, whether from employment, business ventures, investments, or any other source, will be allocated to the Husband. This percentage will be applicable to all income earned during the course of their marriage unless otherwise agreed upon in writing by both parties.”

Can you help me add language to a marital settlement agreement?

I understand you need to make additions to a marriage form. Can you please specify what kind of additions you are looking to make?

I want it to be stated that every income that my wife receives, I will have 30% of every income.

Are you looking to add information about assets, children, or any other specific details to the marriage form?

Yes.

Is there anything else the Family Lawyer should know before I connect you? Rest assured they’ll be able to help with your requested addition.

No.
