Regarding the house title wording, it may different as you thoug

If the house deed as hu*****and and wife, one party goes, the remain got the house. If the deed didn't say as "hu*****and and wife", it will depend upon will.

The performing role as priority as below:
1.House deed
2.will

If the will against House deed, go with deed.

I did consult the lawyer when I did my will. What ever, I think you should have a will since you have your kid...

Thank you!
