This is a regular payment from one party to the marriage or civil partnership to the other, and any Order for spousal maintenance will form part of the financial remedy Order on divorce or dissolution of civil partnership.
There is no set formula for deciding how much spousal maintenance is to be paid. In broad terms, periodical payments are calculated by balancing the income/earning capacity of the parties against their reasonable needs.
An Order for periodical payments must end when the person receiving the payment remarries or forms a subsequent civil partnership, or when either of you dies.
Where possible, you should look to achieve a clean break. This is a settlement where there is no spousal maintenance or where spousal maintenance ends at a set point in the foreseeable future (known as a deferred clean break). Sometimes, this is achieved through capitalised maintenance, i.e., the payee receiving more capital from the settlement instead of maintenance.
