In 2000, Ted was married to Wilma, with whom he had a child, Cindy. Wilma had a young son, Sam, from a prior marriage. Ted typed a document entitled "Will of Ted," then dated and signed it. Ted's will provided as follows: "I give $10,000 to my stepson. I give $10,000 to my friend, Dot. I leave my share of all my community property to my wife. I leave the residue consisting of my separate property to my daughter, Cindy. I hereby appoint Jane as executor of this will."

Ted showed his signature on the document to Jane and Dot, and said, "This is my signature on my will. Would you both be witnesses?" Jane signed her name. Dot was about to sign when her cell phone rang, alerting her to an emergency, and she left immediately. The next day, Ted saw Dot. He had his will with him and asked Dot to sign. She did.

In 2010, Wilma died, leaving her entire estate to Ted.

In 2011, Ted married Bertha.

In 2012, Ted wrote in his own hand, "I am married to Bertha and all references to 'my wife' in my will are to Bertha." He dated and signed the document.

Recently, Ted died with an estate of $600,000, consisting of his one-half community property share of $300,000 in the $600,000 home he owned with Bertha plus $300,000 in a separate property bank account.

What rights, if any, do Bertha, Sam, Dot, and Cindy have in Ted's estate? Discuss.

Answer according to California law.
