Exclusive 0226_candy_spelling_article_tmzCandy Spelling — one of the richest people in Beverly Hills — is a SQUATTER  … who refuses to leave her fancy L.A. condo … and now her landlord is trying to evict her, this according to a new lawsuit obtained by our sources.

Spelling is in a war with the owner of the pad she”s been renting while her $47 million L.A. penthouse is under construction … and now the owner wants a judge to force Candy out of the $28k-per-month unit.

According to the court docs, filed on February 22 in L.A. County Superior Court, the company that owns the unit — located at the famous Carlyle building — claims Candy”s lease ended on January 31st … and she”s refused to vacate.

Of course, Candy is calling BS — in legal papers she filed on Feb. 19, Spelling says she extended the lease for 6 months … and even paid for the month of February.

Besides the eviction,  the owner of the unit is demanding $933.33 for every day Candy overstays her welcome.

Rich people problems.
