There were no constraints defined on the tables. Can I do it this way?
ALTER PROC spDeleteBillingContract (@BillingContractID INT)
AS
DELETE FROM TaskOrderCharge WHERE TaskOrderID IN
(SELECT TaskOrderID From TaskOrder WHERE
BillingContractID=@BillingContractID)
DELETE FROM TaskOrderFunding WHERE TaskOrderID IN
(SELECT TaskOrderID From TaskOrder WHERE
BillingContractID=@BillingContractID)
DELETE FROM TaskOrder WHERE BillingContractID=@BillingContractID
DELETE FROM BillingContract WHERE BillingContractID=@BillingContractID
RETURN
