After the death of John III of Brabant on 5 December 1355, his daughter Joanna and her husband, Wenceslaus, succeeded him as rulers of the duchy.

As an old man he led the successful opposition to the selling of a section of crown land to Sweder of Abcoude, lord of Gaasbeek.

A group led by Sweder's illegitimate son ambushed, beat, and mutilated Everard on the road from Lennik to Brussels.

[2] Everard is commemorated by a monument sculpted by artist Julien Dillens (1849–1904), which is located on Charles Buls street in Brussels, just off the Grand-Place.

It is said among locals that the statue of Everard t'Serclaes brings luck and grants the wishes of all who touch it.
