At any time before the property is sold, approved security may be entered for a stay of proceedings until the expiration of one year after the date of filing the claim. The entry of such security by the owner, before the entry of judgment on the claim, shall be equivalent to an admission by him that the property is liable for the claim. After the stay has expired the claimant may proceed upon the claim and the bond given, separately or simultaneously.
