I may be overthinking things but can someone please clarify how obtaining spousal information on applications for individual credit in community property (WA specifically)states work?

If I am married and want to apply for unsecured credit in my name only, can my creditor require my spouse's information and signature on the loan application?

What about individual credit secured by collateral held in my name only?

I don't believe we always collect spousal information on borrower's spouses if the loan is applied for under individual credit.
