THE family of Michaela are reported to be suing the hotel in which she was murdered while on honeymoon, for damages which could top €1.5million.
The 27-year-old newlywed was strangled in her room at the former Legends Hotel in Mauritius in January last year.
Two hotel workers accused of killing the daughter of Tyrone GAA manager Mickey Harte were cleared of her murder earlier this year. Former Legends employees Sandip Moneea and Avinash Treebhoowoon were found not guilty of her murder by jurors at the island's Supreme Court in July.
Now Mrs McAreavey's widower John and the Harte family have launched civil proceedings against the Lux Hotel Group which is the re-branded name of the hotel.
The basis for the case is understood to be that the hotel failed to provide a safe place for the young teacher to stay.
It is also understood the majority of any compensation awarded would be donated to a charity -- The Michaela Foundation -- set up in memory of the Tyrone woman.
The Michaela Foundation was created to help children in need of support and education.
It is believed the claim was lodged at the Supreme Court in Mauritius on Friday.
In the claim, Mr McAreavey says he knew Michaela for seven years and the couple got engaged in Paris in 2008. The widower, from Co Down, said they had planned to have four children together. A number of fixed damages and expenses are listed in the court papers.
They are understood to include the cost and funeral expenses of Mrs McAreavey's funeral (€22,000). flight expenses (€19,600), legal expenses (€30,747) and professional counselling services (€13,000). The total of the bill is believed to be €91,558.
The remainder of the claim centres on Mrs McAreavey's projected earnings and moral damages.
The McAreavey and Harte families have declined to comment.
