When you originally buy the house, you will need the transfer deed to match the mortgage deed, so that will be only your name.
Anybody living in the house that is over the age of 18 will have to sign a standard form as an occupier. This is a standard requirement from lenders..
Your standard sale / buy contract is exactly that, standard. Whomever is buying the house (with the mortgage) is the person that is listed as owner. Your children can have their interest in your house protected through a will, which you should draw up as well now that you will have a house. If you wanted to buy a house for your children, if you pay cash, you can "gift" it to them, putting it in their name.
After you finish buying the house and registering it, you can do another transfer deed and with the mortgage lenders approval, add your husband as a proprietor only. There are usually covenants to add that he will take care of the mortgage if anything happens to you, wording to protect the bank's interest.
I am now a proprietor in our house and we didn't take out a new mortgage. The mortgage is in my husband's sole name.
This is just what I've been through and what I've learned working for a solicitor.
Good luck!
