As an aside, and not wishing to start separate topic, my wife informed me today that her aunt (not the boy's mother) asked her to countersign a military guarantor document on behalf of her cousin who's soon to join the Thai army, although not sure whether conscripted or voluntary, but she declined to sign because a) she's no idea what she's guaranteeing; and b) she spends most of her time in the UK as a British citizen.
I'm glad my wife had her wits about her today. The boy's mother is dead but his father is still alive and feel like my wife's aunt tried to bully her into being a guarantor. We're not angry, but we're not stupid.
Anyone heard of this guarantee and what it entails? Surely, there's some form of financial guarantee involved, otherwise it would be pointless.
