What is the name of your state? Pennsylvania, Can a co signer repo an auto because the user is not making the payments for three months in a row?
First party refuses to reply to co signer and payments are becoming financially challenging.
Yes, under certain circumstances you could lawfully repossess the vehicle! BUT only if:
1. You co-signed the loan strictly as an accommodation. (Meaning you never received any material benefit from the loan. Example: The vehicle was purchased for the sole purpose, use and benefit of the primary obligor and has never been registered nor title issued in your name), and
2. If you were to pay the lender the entire balance of the loan.
If such conditions are present then by paying off the loan you would be
subrogated to all the rights of the lender including the lender's security interest in the vehicle and the right to repossess and dispose of the collateral in the manner required by Pennsylvania law (i. e. , in a reasonably commercial manner) and the right to seek a deficiency judgment against the primary obligor.
The hitch here seems to be your present inability to pay off the loan. Unless you are able to do so, your legal remedies differ and will be in the nature of suing the primary obligor for contribution, but absent the right to repossess the vehicle.
