Ireland Update: Prohibition On Third Party Guarantees Removed

Ireland's updated AIF Rulebook now allows Qualifying Investor Alternative Investment Funds (QIAIFs) to guarantee third-party obligations, fundamentally changing how fund finance structures operate.

A significant change now permits Irish Qualifying Investor Alternative Investment Funds (QIAIFs) to grant guarantees in favour of third parties, simplifying fund finance structures across a range of transactions.

Background

Ireland transposed AIFMD II on 1 May 2026. Separately, the Central Bank of Ireland published its updated AIF Rulebook, which sets out the operational requirements for alternative investment funds authorised in Ireland, on 5 May 2026.

A key change introduced by the updated AIF Rulebook is that a QIAIF may now guarantee the obligations of third parties.

Previously, the AIF Rulebook provided that a QIAIF may not act as a guarantor in respect of a third party. For many years, this was broadly interpreted as prohibiting the giving of guarantees or security by a QIAIF in respect of the obligations of any party other than itself or a wholly owned or controlled subsidiary or limited partnership (LP).
