The former President's coffin, draped in the national flag, has been placed inside the Parliament surrounded by four Vigil Officers.
Professor Richard's wife, Dr. Jean Ramjohn-Richards, and his daughter, Maxine, were among the first to pay their respects. They then took up position towards the left of the open coffin to receive persons coming in.
The first among those persons was the President of the Senate, Christine Kangaloo. She was followed by Speaker of the House Bridgid Annisette-George.
Prime Minister Dr. Keith Rowley arrived to pay his respects to the late President and signed the condolence book just after 10am.
Chief Justice Ivor Archie followed soon after.
Opposition Leader Kamla Persad-Bissessar and Opposition MPs were also among those paying respects.
