If we don't have a primary key and unable to create a foreign key we need to wirte a function which validate the other table and call this in check constraint.
SIMPLY: Calling function under Check constraint.
alter table YourTable 
add constraint chk_CheckFunction 
check (dbo.CheckFunction() = 1)
create function dbo.CheckFunction() 
returns int 
as begin 
    return (select 1) 
end
