The liquidators of Mount Carmel Hospital have been instructed by the National Asset Management Agency to repay deposits to expectant mothers.
However, only deposits paid to the hospital can be repaid by the liquidators.
Deposits paid to consultants are a matter for individual consultants.
Repayment will be decided on a case-by-case basis, depending on how much service has been received.
However, any balance will be given back.
The liquidators have also been instructed to pay all staff in full, until the end of January.
Unions representing workers at the hospital have been told that the liquidators will need 48-72 hours to get to grips with the facility.
Staff are expected to be called to a meeting again early next week where they will be given further information about when redundancies will begin.
The first are expected as early as next Friday.
Staff will be paid statutory redundancy.
Unions have said the employment landscape for health workers is worrying, with the HSE operating a targeted voluntary redundancy scheme and the private sector struggling.
From today there will be no further elective surgery at the hospital, but the commitment to obstetric patients will remain over the next week to two weeks.
