If you apply for ILR based on 10 years residence, your spouse and children under 18 will have to switch to FLR M and meet the requirements. This will also reset their clock to zero and a new 5 year route (2 x 2.5 year visas) before they will qualify for ILR.

Children over 18 will have to find a visa route they qualify for in their own right. They won't qualify for FLR M as your dependents.

If you apply for ILR based on 5 years tier 1, you over 18 children can also apply provided they are not leading independent lives.
