I live in a flat in a building where 10 owners have shared responsibility for repairs. We are having urgent repairs done which I have organised - quotes etc,etc. One party has not yet paid their share. They own a commercial property so do not live on-site and my only way of contacting is via email. I can cover their share to ensure the final bill is paid (and will inform other owners so they can contribute). My question is how can I get this person to cough up? I am in Scotland. Is the only realistic option small claims court?
