You probably have little chance of winning if you don't have physical proof that gives absoultely no doubt the damage was there before you moved in. The landlord may or may not also have that kind of proof that is required and in small claims cases when it's one persons word against another sometimes the case is dismissed, other times the judgement is for the plantiff.
It's not going to be like Judge Judy on TV where both parties get to argue back and forth and are given all the time they want to speak etc. If it gets to the court date the proceeding is going to be very cut and dry. The whole thing in front of the judge might take 3 minutes until he/she makes a decision.
This could really go several ways. And it depends what the damage is and what it truly cost the landlord to repair it. $950 to repair a wood floor doesn't sound right to me. You left some information out that is important to know.
How big was the floor?
Was it the entire floor that was damaged or just an area of it?
Was the entire floor repaired or just the damaged section?
What exactly was the damage?
What was done to repair the floor?
Who did the repairs? A contractor or did the landlord do it them self?
The judge isn't going to be interested in hearing either side's story they will have mutliple cases to get through. They want proof; photos, receipts, witness statements.
What I suggest is, this sucks especially if you're not at fault but having a small claims against you can show up on a credit report or background check, is work something out with the landlord and pay him payments toward it. If he/she accepts you being willing to do that and avoid going to court (which is likely - taking it to court is costly) then try to negotiate the price. If they want $950 offer a total of $700 in $50 to $100 payments.
If they accept a payment plan or a lower payment get a receipt, that is settling it out of court. Then they can't take you to court.
It's accepting fault for something you may not be at fault for but if if this does go to court and you lose it's going to be in the way of you getting in to other homes later. Keeping it out of court avoids all of that headache for you even if you're not at fault and it costs you money. If you make this landlord happy you possibly have a good reference for future rentals and other things.
