If you are single (whether previously married, divorced, widowed or in a civil partnership that has been dissolved), you can marry anyone except:
- someone already married or in a civil partnership; or
- someone you are not allowed by law to have sex with because of age (they must be over 16 years), or relationship (such as grandparents, parents, brothers, sisters, children or grandchildren); or
- other relatives (uncles, aunts, nephews or nieces; stepchildren and step parents; your ex mother-in-law or ex father-in-law etc).
