Asking for a friend...

Hello Nairalanders! Happy weekend... Please a friend of mine had his divorce decree from the High court in Lagos but not duly registered. Now he need to provide his divorce decree certificate to the embassy but the problem is that embassy now make verifications of divorce decree certificates to ascertain if its genuinely done and he has already uploaded the decree certificate on the embassy's system during his application . Please, anyone with genuine suggestions or solution... Thanks
