No. The only way to know the relationship of fencing to the title boundary is to have a title re-establishment survey carried out by a licensed land surveyor. It is common for fencing along a series of properties to have a common trend in a particular direction meaning your fence-to-fence width may match title-to-title width but the fence-to-title relationship be significantly different. Assuming the fence-to-title relationship can lead to huge blunders costing you dearly.
