The Beatles legend, who split from Heather Mills last May, has decided to put his tour on hold to look after the couple's three-year-old daughter Beatrice.
Paul said: "I'm going to do bits and pieces to support the album, but it won 't be a major tour until possibly next year, and that's down to personal circumstances."
The 64-year-old musician had hoped to fully promote new album "Memory Almost Full," which is released on June 4.
However, his lawyers reportedly warned him to remain in the UK until his divorce is finalized.
A source told Britain's Sunday Mirror newspaper: "Paul shares custody with Beatrice. If he went on tour it would be impossible to look after his child."
"And if the divorce is not finalized Heather could argue she should get some of the profits because the album was inspired by Paul's time with her."
Paul revealed his painful divorce has brought his family closer together. He said: "I'm going through struggles but I am feeling pretty good."
"In difficult moments like this, it's when a loving family shines through. The real positive out of this marriage is my beautiful baby daughter."
Meanwhile, Heather, 39, and Paul met in London on Friday (May 18, 2007) to call a truce for Beatrice's sake.
Paul reportedly vowed to finalize their divorce by early next year, while Heather agreed to remain in the UK with Beatrice and scrap plans to launch a career in the US.
The estranged couple are even said to have agreed to celebrate Paul's 65th birthday as a family next month.
