Only consideration to mention, which sounds a little cruel to the bike rider.(posted 7860 days ago)Has the court demanded that the rider be paid now?
If no time limit has been set, then taking out a second mortgage would mean your friends are paying interest!, would a monthly payment to the rider not be a better method thus avoiding interest and therefore more saving money?
As the previous advice says they need to seek legal advice.
Good luck to your friends.
