Kevin Federline, former spouse to Britney Spears, is contemplating legal proceedings regarding his intention to relocate to Hawaii with their two teenage sons, Sean Preston, 17, and Jayden James, 16, with whom Spears has reportedly had no contact for more than a year, RadarOnline.com has discovered.

Federline set a Friday cut-off for Spears' legal team to consent to the proposed relocation.

The sole custodian of Sean Preston and Jayden James, Federline has implied he will seek court intervention if the 'Gimme More' songstress fails to formally agree to the relocation by the week's close.

Mark Vincent Kaplan, Federline's legal counsel, insists that Mathew Rosengart, representing Spears, has been informed repeatedly about the intended move.

According to Kaplan, numerous attempts have been made to secure Spears' agreement through her attorney, but these efforts have gone unanswered.

The pressure isn't solely on Spears, however.

Kaplan contends that Federline is scheduled to leave for Hawaii on August 1, with Spears' non-response obstructing his ability to secure rental accommodation.

Further complicating matters, Victoria Prince, Federline's wife, is facing a ticking clock to accept a job proposal with a university in the islands.

Given Federline's full custody of the pair's sons, he believes there is no valid rationale for Spears to decline the move.

Federline also pointed out that his custodial rights inherently grant him physical custody of the children.

Adding to the tension, Federline made an incisive remark about Spears' alleged lack of interaction with her sons for over a year.

Although insiders from Spears' side conveyed to the media outlet that the singer had no objections to her sons moving to Hawaii with their father, without official permission from their mother or a court mandate, Federline is unable to proceed.

If Spears doesn't comply with the Friday deadline, Federline is ready to take it to court. Kaplan confirmed his intent to submit a relocation request to the court in the event of Spears' non-compliance.
