Repossession question?

Of course, it's perfectly legal. You signed a contract and have defaulted on that agreement. The bank has called the loan. They don't have to allow you to just bring the account up to date.

I suspect that you've missed more than just a few payments. Normally a bank would let you bring the account up to date if it were only a couple missed payments.

They will likely repo the bike and you will be responsible for the balance of the loan, plus whatever legal expenses for the repo. Maybe you should try to sell the bike and then just pay out of pocket whatever the difference between the loan balance and the sale price.

You don't lose the bike and lose the money.

If you lose the bike = you owe the total amount due and they will come after you.

If they still decide to repossession and you have made payment = the amount they come after you for is less the payment you made.

Yes it is legal. They are under no legal obligation to accept your terms once your hubby materially breached the original contract.
