dole and means test
Unemployment Assistance is a means tested payment, as a result (once her partner moves in) they will assess her claim for UA based on her partners income (regardless of expences).
She may very well lose her payment (assuming her partner has anything close to an average industrial wage). If this is to be the case she should enquire about her entitlement to sign for prsi credits.
Note: she will also have to inform her Health Board, as a result her Medical card (if granted on income grounds) may also be affected.
If in Local Authority housing, her rent will also be reassessed.
Local Authorities, Social Welfare, Health Board will view them as a couple. Unlike Revenue, who will view them as two single people, meaning her partner will be unable to gain any tax benefit afforded to married couples.
You just can't win!
