Laws regarding squatters vary on a state-by-state basis. In California, ownership could be granted to a squatter who pays taxes on a property for five years through adverse possession and tenancy rights could be granted after 30 days.

One of the latest squatter stories out of California was reported by Fox News Digital in September, after two Hollywood Hills mansions were overtaken. 

"I would like to apologize to the people of Los Angeles, and especially to my neighbors. What’s happened to the two properties I own is unacceptable, and no matter what caused it, I own the houses," John Powers Middleton, film producer and son of Philadelphia Phillies owner John S. Middleton, previously said in a statement sent to Fox News Digital.

"What’s happened to my property is criminal, and I hope everyone caught will be prosecuted to the full extent of the law. No one in Los Angeles should have to put up with squatters and vandalism that are out of control," Middleton also said. 

In March, Fox News Digital reported on a $5 million Beverly Hills home that was invaded by squatters. The real estate agent of the home called the police, but was told that it was a "civil matter" at play, as the squatters had what they claimed to be a rental agreement.

"These squatters are very clever, and they will come up with fake leasing documents or a fake story about how someone let them in, the landlord let them in," Daniel P. Phillips, a real estate litigation partner at Belkin, Burden and Goldman in New York, previously told Fox News Digital. 

Several California-based law firms note on their websites that after 30 days, ownership can not be granted to a squatter, but tenancy rights can be. 

Once a landlord provides a squatter with a written notice to vacate the property and they don't leave, an unlawful detainer lawsuit has to be filed with the court. Trials often take several months to reach a conclusion.

While squatters cannot gain legal ownership of a property after 30 days, they could gain ownership through adverse possession after five years of paying taxes on the property.

ADVICE FROM PROFESSIONALS ON PROTECTING YOUR HOME AGAINST SQUATTERS

Adverse possession, which has become known as "squatter's rights," is not unique to the state of California, but each state does have a different period of time and other requirements regarding when it could be claimed. 

Adverse possession doesn't always relate to a squatter. It could also be claimed unintentionally, such as in the case where a homeowner puts up a fence to mark property boundaries, but accidentally dips into their neighbor's land. The homeowner who constructed the fence could claim adverse possession of the land they built on. 

There are general requirements that are typical for each state, including the possession being open and notorious, but specifications like how long someone, such as a squatter, must be in possession of the land vary. In California, five years of occupation and payment of taxes is required, according to FindLaw.com.

HANDYMAN WHO TURNED THE TABLES ON SQUATTERS CLAIMS HE'S HACKED THEIR SYSTEM AND CAN HANDLE YOURS TOO

The "Squatter Hunter," whose real name is Flash Shelton, dealt with squatters personally when his mother's home was overtaken. When he reached out to law enforcement, he was told the matter was a civil one. 

After researching the laws, he flipped the script by using them in his favor. 

"I learned everything about squatters over the course of a few days… I figured out that if I could establish the rights [to the home] before them and I could switch places with them and become their squatter, then that would work," Shelton previously told Fox News Digital.

"It was just switching places with them, becoming their squatter, locking them out, putting up cameras and telling them that I would prosecute if they broke back in — [that] was enough," he also said. 

Shelton's story went viral on social media, and he now helps others who find themselves in a similar situation to the one his mother was in.

He has also spoken about law changes he feels would help protect homeowners. 

"The states that are friendly to squatters — those squatters are just assuming tenant rights. So what we need to do is separate it out," Shelton told Fox News Digital. "And if somebody enters a house illegally, regardless of how long they've been there, that should be a crime."
