He arrived in UK on 3/2/17 so assume we can send this off 28 days before 3/2/22?
That's correct.
We are using form FLR(M) - assume this is the correct one?
No, that's the wrong form. FLR(M) is for a 2.5-year temporary extension visa, not ILR.
The form you need for ILR is SET(M):
https://www.gov.uk/government/publications/application-to-settle-in-the-uk-form-setm/apply-online-form-setm"Do you have any children whose parent is not your partner?" - does that only refer to children under age of 18 - we both have adult children in their 30s and 40s but we wouldn't class them as children so have said no - is this correct?
That's correct - only children under 18 need to be included (because if the visa falls for refusal, they look at whether you have any UK citizen dependent children under 18 whose lives would be badly affected if you had to leave the UK).
"Do you own or rent your home?" - does he put "Neither own nor rent" if he lives with me but isnt named on the mortgage (He didnt have a job when we got the mortgage so the house is in my name only) (if so, would I need to provide letter stating that he lives with me?)
Not correct. They are asking 'you' as a couple, not the applicant as an individual. The correct answer is 'I own' because as the sponsor, you own the home you both live in.
The options mean:
'I rent' = you as a couple rent your home from a landlord. Neither of you owns the house.
'I own' = either the applicant or the sponsor (or both jointly) own the home you live in. It is not rented and it does not belong to anyone else.
' I neither rent nor own' = you as a couple do not rent or own the home you live in. Instead you live in someone else's house which they own, for example, a family member or a friend (i.e. you live with your parents), and you are basically just a guest in their house.
