Would previous convictions prevent someone from fostering?
A previous conviction will not necessarily disqualify you from fostering, however, this would depend on the nature of the conviction and when it occurred, among other factors.
Certain offences such as indecency, importation/possession of indecent images of children or any other sexual offences will preclude an enquirer from being considered as a foster carer.
The guiding principal in processing applications where there are recorded convictions is that the safety and protection of children is paramount.
Garda vetting is completed early in the application process and it is important you disclose any convictions as soon as possible so as a decision can be made on whether or how it may affect your application.
