The FAI have confirmed that they have received a letter from St Patrick’s Athletic in relation to UEFA Club Licensing.
It is believed the matter is in relation to Waterford FC and their place in the Europa League this year.
The Blues finished fourth last season to qualify for Europe, but a club must be in existence for three years to compete in UEFA competitions.
Waterford were reformed as a new company after owner Lee Power took over in late 2016.
St Pat's would be next in line if Waterford were not granted a UEFA licence.
The FAI statement read: "The Football Association of Ireland can confirm it is in receipt of a letter from St Patrick’s Athletic in relation to UEFA Club Licensing and is looking into the matter."
St Patrick’s Athletic would not comment on the matter.
