Whatever your contract says; some contracts say one minute part midnight on the due date; and some have a 30 day grace period, some really really don't want the car back, ( banks mostly) and they will work with you to get caught up.

As SRDEsq states whatever your contract says, you need to read it, the bottom line is the bank wants thier money, usally they will work with you, but if they are wanting to repo the car, then you have probary been missing to many payments, and that can hurt because then you have late fee's on top of your payment. The thing with your car being repoed, is are the creditors doing it legally. So many people are unaware that they do it illlegally. You can go online to laws on reprosession of cars and go to your state. Some of the things that I have found in regards to a car being repoed is the creditor has to send you notice of their intent, also in some states the law requires the creditor to let you no when the car goes to action giving you a chanage to bid on it.If they do not do this you can consult with a lawyer, they may owe you money instead of your owing them. If your car has been repoed check the laws in your state, if it has not been you might want to make up any past due payments and try to get a deferral for a month to help you catch up, your allowed three for the time of your contract.

My daughter had not missed any payments and they still repossessed her vehicle, I do not know why, she has all of the receipts where she has made a payment.
