Legal separation

Does my husband have to physically move out of the house in order to proceed with the lagalities of the legal separation?

Can you please tell me what are the steps I should take once we have discussed and sort of agreed on the asset separation to formalize the legal separation?
he insists in staying in the house while it sells, but I am worried that this may not be the right thing to formalize the legal separation.
Thanks a lot

Yes, you must be living separate and apart in different residences.
If you agree to an asset distribution you should see an attorney to evaluate the distribution and get an agreement drafted.
