My partner is withholding money from me, what can I do?
A lot will depend on whether the relationship between you and your partner has broken down and if there is going to be a divorce or a separation. If you do not want a divorce/separation, then you should perhaps talk to your partner, or consider using the services of marriage guidance or mediation to try and resolve the matter and come to an amicable solution. If, however the problems are such that you believe a divorce/separation is inevitable, then consideration can be given to obtaining maintenance for you. If you have children together and the children live with you, this may mean that you can get child maintenance for the children from the Child Maintenance Service, or it may be that your partner has an obligation to pay you maintenance known as spousal maintenance. Spousal maintenance however would not be an option if the two of you were not married.
A separation may mean that you are entitled to other benefits in your own right such as child benefit, tax credits etc. You would be best to take fairly urgent legal advice to get guidance on your individual circumstances and the options open to you.
