I own my home and I have a new husband who has nothing to do with the home, can i take out an equity line with his involvement

Yes but his name will have to be added to title.

Yes,as stated his name will be added to title- if he is to be on the loan also, he willhave to qualify with his income and debts along with yours-

California is a Community Property State.IF he is NOT on Deed & NOT on Mortgage Note & you plan to keep it that way- that is fine, you can.However, there are still forms he would likely need to sign acknowledging that you are restructuring the note on your property.

Normally, anytime your use someone to qualify for a loan & they are involved in the approval process normally they are added to the Deed. They can be quitclaimed off after the loan is completed.

Yes, you can as long as his name is added to the title/deed of the property.

Sure... No problem...

He would need to be added to title. Be advised that different states will have different requirements.
