Uh oh! Beyoncé and Jay-Z got a little more than they bargained for when they purchased a multi-million dollar mansion in Bel Air.

Apparently, in purchasing the property, the couple also inherited some legal drama.

Let's back up for a moment, shall we?

The previous owners had entered into an agreement to install a fourth pool on the lot. Yes, we said fourth pool ...

According to The Blast, the former owner never paid the bill ... which was around $90k.

Due to failure of payment, the pool company has filed a construction lien against the property.
