Former Thin Lizzy guitarist Gary Moore left an estate worth over £2m, according to probate records.
The Belfast-born star died of a suspected heart attack in February as he began a holiday in Spain.
Records released last week show that Moore's estate was worth £2.077m but this was reduced after liabilities to a net figure of £1.021m.
The High Court in England granted a temporary order allowing his executors power to run his companies, Orionstar and Bonuswise, pending a final settlement of his estate.
Moore, with an address in Hove, England, had two sons from a former marriage and a daughter from his relationship with Jo Rendle. It is not known if he left a will. The 58-year-old had a successful solo career as a singer and guitarist but is best remembered for his time with Thin Lizzy.
Moore died hours after checking into the five-star Kempinski Hotel on the Costa del Sol.
