Police consider the husband of slain Melbourne mother Karen Ristevski to be the "number one suspect" for her murder, his lawyer has declared, only hours after detectives confirmed her body had been found.

Leading criminal lawyer Rob Stary said Borce Ristevski visited his office on Wednesday morning, seeking guidance on what the discovery of Ms Ristevski's remains could mean to the investigation.

On Tuesday night Mr Ristevski and family members hatched a plan for him to leave the family home and avoid scrutiny from the large media scrum outside, as family members delivered McDonald's.

The Age has been told that Mr Ristevski and several other family members wept after hearing the news that the body found on Monday was that of his wife.
