Is verbal agreement also valid?

Questioner

I have a private lease car that I took out with a dealer. Here the agreement was made that the garage (the same dealer) would first ask permission from the leasing company for maintenance. If there was no agreement, I would be informed of this before the appointment. After the appointment I asked again if everything was in order. Yes, this is the case. Now more than a month later, I am called that something is not reimbursed (the alignment). I have indicated that I assume that if they indicate that there is an agreement, and I specifically ask again afterwards, everything would indeed be in order. Now the garage says, yes, you will have to pay anyway and what would you have done differently? Not have it done? To which I indicated that I would probably have had the car aligned somewhere else. Do I still have to pay these costs or am I right that they verbally agreed that everything is in order?

Lawyer

An oral agreement is in principle legally valid, but there may be a problem of evidence. If the other party denies the existence of the agreement, you will in principle have to prove that the agreement was made and if there is nothing on paper and/or there are no witnesses who can confirm the existence of the agreement, that can be difficult.
