Can anyone advise/ share their knowledge re the following circumstances: my step- brother is in the process of getting divorced and is quite likely to be awarded custody of his two school- aged children (wont go into circs- that would be another thread). His stbxw has moved to another area and is co- habiting with new boyfriend. She isnt working but claims the child benefit plus other benefits (has a back problem so maybe disability? - not really sure). They currently have 50/50 custody of kids. My step- brother is self employed - not a huge earner. The stbxw boyfriend (renting a house together) is wealthy. What happens if my step- brother gets full custody (with stbxw having access every other weekend/hols). Would stbxw have to pay any maintenance? Would the co-habitee's earnings have any bearing on what/if she paid?
Hope that makes sense. Thanks for any help/knowledge/experience.
