Nanette Kinkade, who filed for divorce from her husband of 28 years in 2010, and his live-in partner, Amy Pinto, have been in a war of words over his will ever since the painter died from an accidental overdose on 6 April (12).
However, on Wednesday (20Dec12), the two women in his life came to an undisclosed agreement over the rights to his California mansion, warehouse of works, and the remainder of his funds.
A joint statement, released by their lawyers to local publication The San Jose Mercury News, reads: "Putting Mr. Kinkade's message of love, spirituality, and optimism at the forefront, the parties are pleased that they have honoured Mr. Kinkade by resolving their differences amicably."
The landscape painter passed away last month (Apr12) at his home in Monte Sereno, California.
Autopsy results showed Kinkade stopped breathing at the property after consuming Valium and alcohol, according to NBC Bay Area News.
The Santa Clara County medical officer also ruled "hypertensive and atherosclerotic heart disease" contributed to the tragedy.
Kinkade, one of America's most-collected artists, battled alcoholism during the final five years of his life following the breakdown of his marriage. He attempted to curb his drinking but struggled to quit altogether.
Following his death, his estranged wife Nanette Kinkade issued a statement which read, "Thom provided a wonderful life for his family. We are shocked and saddened by his death."
The artist, one of America's most-collected living artists, passed away at his home in Monte Sereno, California on Friday (06Apr12).
His family attributed his death to natural causes and an autopsy is to be conducted on Monday (09Apr12).
His wife Nanette Kinkade says in a statement, "Thom provided a wonderful life for his family. We are shocked and saddened by his death."
Kinkade, who hailed himself as a "painter of light", was best known for his serene and sentimental paintings of cottages and seascapes.
His body of work has been heavily criticised by art experts, but Kinkade was thought to earn as much as $100 million (£62.5 million) in annual sales.
