You need 'registrars' ink for permanent records and is the only ink to use on official documents.

It writes blue but then oxidises to black. You can get it from a multitude of sources/manufacturers. Here is an example:

Any fountain pen will suffice.

The register's ink will definitely do the job, but it is hard on pens.

An alternative would be noodler's bulletproof series.
