This has happened before - just agree a reasonable price for it and for one dont feed the lawyers!
In 1994, The Irish Times established a website called Irish-times.ie; it was the first newspaper in Ireland and one of the first 30 newspapers in the world to do so. The company acquired the domain name Ireland.com in 1997, and from 1999 to 2008, used it to publish its online edition. It was freely available at first but charges and a registration fee were introduced in 2002 for access to most of the content. A number of blogs were added in April 2007 written by Jim Carroll, Shane Hegarty, and Conor Pope. On 30 June 2008, the company relaunched Ireland.com as a separate lifestyle portal and the online edition of the newspaper was now published at irishtimes.com. It was supplied free of charge, but a subscription was charged to view its archives.
On 15 October 2012 John O'Shea, Head of Online, The Irish Times, announced that the ireland.com domain name had been sold to Tourism Ireland, and that the ireland.com email service would end on 7 November 2012. The domain name was sold for €495,000. The ending of the email service affected about 15,000 subscribers.
The newspaper announced on 17 February 2015 the reintroduction of a paywall for its website, irishtimes.com, beginning on 23 February."
