The whole Murray family will be travelling to Ghent to watch Andy and Jamie play in the Davis Cup final.
Some British fans have decided against making the trip to Belgium because of the security situation in nearby Brussels, while Tim Henman will also be staying at home instead of bringing his family.
But the Murrays are due to arrive in Ghent en masse for the occasion, which could see Andy and Jamie win all the rubbers needed to clinch a first Davis Cup title for Great Britain since 1936.
Judy Murray told ESPN: "Everybody's going - my parents, my brothers, my sisters-in-law, my nieces, my two best friends, and also Jamie and Andy's dad, and his side of the family.
"We will be there in force because it's a huge moment for British tennis but it's also a huge moment for our family.
"You always have to be aware of what's going on with the security. What happened in Paris was so shocking but, if you live in fear of what might be, you would never do anything.
"Everything that we've heard from the LTA's security specialist, who has been in Ghent for the best part of a week now, is that it's business as usual. We have to trust that and go out and hope that there is no incident and that we have a great final."
The clash between Belgium and Britain will begin amid tightened security at the Flanders Expo on Friday.
