If my company rent out investment property to a firm and they are on a year lease and they only paid for 6 months but stayed there for entire year,

thus owing for the additional 6 months, that they stayed there did not pay. I sued them in court of law and I received a judgment against them but I never received the money. Can I write that off of my partnership F1065 tax return? Is this a bad debt? My company is a partnership.
