Around 25,000 people who were imprisoned in relation to Irish nationalism and terrorism charges have been warned their home and motor policies may be invalid.
The former prisoners include those granted early releases under the Good Friday agreement which freed those people serving sentences related to paramilitary group activities in return for the groups maintaining a ceasefire.
Some of those involved in the peace progress have asked for the convictions to be considered "parked", meaning they are treated as having not happened unless and until the person concerned commits a new offence.
However, the rules don't currently allow for this. The convictions are therefore treated like all others and only considered "spent" after a set period: seven years after the date of conviction for those jailed for less than six months, ten years for those jailed between six months and two and a half years, and never for those jailed for more than two and a half years.
"Unspent" convictions are usually only an issue when applying for jobs, but some insurers refuse to cover people with an unspent conviction. In such cases, the onus is on the customer to tell the insurer about the conviction, even if they aren't specifically asked.
