If spousal maintenance is payable, the amount and length of maintenance would need to be agreed upon. For example, the wife would pay the husband £500 a month for three years.
The financial settlement can also include conditions on the maintenance payment, including if the spouse who was receiving payment lived with a new partner for six months or remarried, then the spousal maintenance would end earlier.
If you have children involved, the spousal maintenance is separate from any child maintenance assessment that you can calculate on the child maintenance website.
