The earliest recorded epigraphic evidence of the Maithili script dates back to the 7th century AD.

It is found in the inscriptions of Adityasena on the Mandar Hill Stone, located in Bounsi, Banka district, Bihar.

These inscriptions, now preserved in the Baidyanath Temple of Deoghar, provide a crucial glimpse into the early development of this script.

[6] Nowadays, the Maithili language is written almost exclusively in the Devanagari script, although Tirhuta is still sometimes used by religious Pundits and some culture – conscious families for writing ceremonial letters (pātā), documents & cultural affair, and efforts are underway to broaden the scope of its usage.

Later on Pusk Bhandar, Laheriasarai managed to forge a set of types and published a few works in Tirhuta, but could not go ahead.

The Unicode submission, for example, only bothered to create new graphic designs for 7 of the 33 letters: ⟨jh, ṭ, ḍh, ṇ, l, ś, h⟩.
